E

.  These are the lubrication points for the delay mechanism.  For every speed from 25 to 

150, this mechanism  delays the shutter blades to ensure that the shutter blades remain 
open for the appropriate amount of time.  If your shutter blades do  not close properly 
when set to 25 speed but work well on  150 speed, the problem most likely lies here.  
Unlike in the pre-war  Shutter,  some of  these  spindles are not easily accessible because 
the tops are blocked by a metal plate.  To lubricate these spindles, force the lubricant in 
from the side of the spindle. 
 

F

.  This lever rides on a cam on the Face Plate.  When you rotate the Face Plate to set the 

shutter speed to B(ulb) or T(ime), this lever sets the mechanism in 

A

 to the proper 

position. 
 

G

.  This lever also rides on a cam on the Face Plate.  It controls the shutter speed from 25 

to 150.
